Antique Sterling Enamel Norway Guilloche Brooch Green

This feminine brooch is made of sterling silver with a wavy guilloche pattern under vitreous glass (kiln-fired) enamel in a beautiful shade of aqua green. The oblong piece has a pretty, scalloped border. The back has a simple c-clasp and is signed "925S," indicating its Scandinavian origins. There is no maker's mark.

Measuring 1 3/8" by 1", the brooch is in very good condition. It does have some minor surface abrasions consistent with age, but there are no cracks or chips to the enamel.
